Carnikava Parish
Carnikava ( Livonian: ''Sarnikau'', german: Koivemund, ''Zarnikau''), previously Sānkaule, is a village and the center of the Carnikava parish of Ādaži Municipality in Latvia. It's located 25 km north from Riga at the mouth of the Gauja River. Carnikava had 4689 residents as of January 2020. The village was first mentioned in Livonian Chronicle of Henry in 1211 as a summoning place of Livonian troops. Later Carnikava grew into a fishermen village, where in the 17th century the first breeding fishery and canned fish factory in the Russian Empire was built. Due to its proximity to the Baltic Sea, several forest lakes, the Gauja and annual fishermen and craftsmanship fairs, nowadays Carnikava is a popular summer resort among visitors from Riga. A notable symbol and long-time specialty of Carnikava has been grilled lamprey, which is also pictured on the coat of arms of the municipality.

Livonian Chronicle Of Henry
The ''Livonian Chronicle of Henry'' ( la, Heinrici Cronicon Lyvoniae) offers a Latin narrative of events in Livonia (roughly corresponding to today's inland Estonia and the northern part of Latvia) and surrounding areas from 1180 to 1227. It was written ca. 1229 by a priest named Henry ( la, Henricus de Lettis). Apart from the few references in the Primary Chronicle compiled in Kievan Rus' in the twelfth century, it is the oldest known written document about the history of Estonia and Latvia. Background Papal calls for renewed holy war at the end of the twelfth century inspired not only the disastrous Fourth Crusade that sacked Constantinople in 1204, but also a series of simultaneous "Northern Crusades" that are less fully covered in English-language popular history, but which were more successful in the long run. Before the crusades, the region of medieval Livonia was a mixed outpost, a mostly "pagan" society where merchants from the Hanseatic League encountered merchants ...

Villages In Latvia
A village is a clustered human settlement or community, larger than a hamlet but smaller than a town (although the word is often used to describe both hamlets and smaller towns), with a population typically ranging from a few hundred to a few thousand. Though villages are often located in rural areas, the term urban village is also applied to certain urban neighborhoods. Villages are normally permanent, with fixed dwellings; however, transient villages can occur. Further, the dwellings of a village are fairly close to one another, not scattered broadly over the landscape, as a dispersed settlement. In the past, villages were a usual form of community for societies that practice subsistence agriculture, and also for some non-agricultural societies. In Great Britain, a hamlet earned the right to be called a village when it built a church. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paleontology
Paleontology (), also spelled palaeontology or palæontology, is the scientific study of life that existed prior to, and sometimes including, the start of the Holocene epoch (roughly 11,700 years before present). It includes the study of fossils to classify organisms and study their interactions with each other and their environments (their paleoecology). Paleontological observations have been documented as far back as the 5th century BC. The science became established in the 18th century as a result of Georges Cuvier's work on comparative anatomy, and developed rapidly in the 19th century. The term itself originates from Greek (, "old, ancient"), (, (gen. ), "being, creature"), and (, "speech, thought, study"). Paleontology lies on the border between biology and geology, but differs from archaeology in that it excludes the study of anatomically modern humans. It now uses techniques drawn from a wide range of sciences, including biochemistry, mathematics, and enginee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Embryology
Embryology (from Greek ἔμβρυον, ''embryon'', "the unborn, embryo"; and -λογία, '' -logia'') is the branch of animal biology that studies the prenatal development of gametes (sex cells), fertilization, and development of embryos and fetuses. Additionally, embryology encompasses the study of congenital disorders that occur before birth, known as teratology. Early embryology was proposed by Marcello Malpighi, and known as preformationism, the theory that organisms develop from pre-existing miniature versions of themselves. Aristotle proposed the theory that is now accepted, epigenesis. Epigenesis is the idea that organisms develop from seed or egg in a sequence of steps. Modern embryology, developed from the work of Karl Ernst von Baer, though accurate observations had been made in Italy by anatomists such as Aldrovandi and Leonardo da Vinci in the Renaissance. Comparative embryology Preformationism and epigenesis As recently as the 18th century, the prev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biology
Biology is the scientific study of life. It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field. For instance, all organisms are made up of cells that process hereditary information encoded in genes, which can be transmitted to future generations. Another major theme is evolution, which explains the unity and diversity of life. Energy processing is also important to life as it allows organisms to move, grow, and reproduce. Finally, all organisms are able to regulate their own internal environments. Biologists are able to study life at multiple levels of organization, from the molecular biology of a cell to the anatomy and physiology of plants and animals, and evolution of populations.Based on definition from: Hence, there are multiple subdisciplines within biology, each defined by the nature of their research questions and the tools that they use. Like other scientists, biologists use t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heinz Christian Pander
Heinz Christian Pander, also Christian Heinrich Pander ( – ), was a Russian Empire ethnic Baltic German biologist and embryologist. Biography In 1817 he received his doctorate from the University of Würzburg, and spent several years (1827–1842), performing scientific research from his estate in Carnikava (german: Zarnikau) on the banks of the Gauja River near Riga. In 1820 he took part in a scientific expedition to Bokhara as a naturalist. In 1826 he became a member of the Saint Petersburg Academy of Sciences. Research Pander studied the chick embryo and discovered the germ layers (i.e., three distinct regions of the embryo that give rise to the specific organ system). Because of these findings, he is considered by many to be the "founder of embryology". His work in embryology was continued by Karl Ernst von Baer (1792-1876), who expanded Pander's concept of germ layers to include all vertebrates. Pander performed important studies in the field of paleontology, bein ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lamprey
Lampreys (sometimes inaccurately called lamprey eels) are an ancient extant lineage of jawless fish of the order Petromyzontiformes , placed in the superclass Cyclostomata. The adult lamprey may be characterized by a toothed, funnel-like sucking mouth. The common name "lamprey" is probably derived from Latin , which may mean "stone licker" ( "to lick" + "stone"), though the etymology is uncertain. ''Lamprey'' is sometimes seen for the plural form. There are about 38 known extant species of lampreys and five known extinct species. Parasitic carnivorous species are the most well-known, and feed by boring into the flesh of other fish to suck their blood; but only 18 species of lampreys engage in this micropredatory lifestyle. Of the 18 carnivorous species, nine migrate from saltwater to freshwater to breed (some of them also have freshwater populations), and nine live exclusively in freshwater. All non-carnivorous forms are freshwater species. Adults of the non-carnivorous ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baltic Sea
The Baltic Sea is an arm of the Atlantic Ocean that is enclosed by Denmark, Estonia, Finland, Germany, Latvia, Lithuania, Poland, Russia, Sweden and the North and Central European Plain. The sea stretches from 53°N to 66°N latitude and from 10°E to 30°E longitude. A marginal sea of the Atlantic, with limited water exchange between the two water bodies, the Baltic Sea drains through the Danish Straits into the Kattegat by way of the Øresund, Great Belt and Little Belt. It includes the Gulf of Bothnia, the Bay of Bothnia, the Gulf of Finland, the Gulf of Riga and the Bay of Gdańsk. The "Baltic Proper" is bordered on its northern edge, at latitude 60°N, by Åland and the Gulf of Bothnia, on its northeastern edge by the Gulf of Finland, on its eastern edge by the Gulf of Riga, and in the west by the Swedish part of the southern Scandinavian Peninsula. The Baltic Sea is connected by artificial waterways to the White Sea via the White Sea–Baltic Canal and to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Russian Empire
The Russian Empire was an empire and the final period of the List of Russian monarchs, Russian monarchy from 1721 to 1917, ruling across large parts of Eurasia. It succeeded the Tsardom of Russia following the Treaty of Nystad, which ended the Great Northern War. The rise of the Russian Empire coincided with the decline of neighbouring rival powers: the Swedish Empire, the Polish–Lithuanian Commonwealth, Qajar Iran, the Ottoman Empire, and Qing dynasty, Qing China. It also held colonies in North America between 1799 and 1867. Covering an area of approximately , it remains the list of largest empires, third-largest empire in history, surpassed only by the British Empire and the Mongol Empire; it ruled over a population of 125.6 million people per the Russian Empire Census, 1897 Russian census, which was the only census carried out during the entire imperial period. Owing to its geographic extent across three continents at its peak, it featured great ethnic, linguistic, re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Livonians
The Livonians, or Livs ( Livonian: ''līvlizt''; Estonian: ''liivlased''; Latvian: ''līvi'', ''lībieši''), are a Balto-Finnic people indigenous to northern and northwestern Latvia. Livonians historically spoke Livonian, a Uralic language closely related to Estonian and related to Finnish. The last person to have learned and spoken Livonian as a mother tongue, Grizelda Kristiņa, died in 2013, making Livonian a dormant language. As of 2010, there were approximately 30 people who had learned it as a second language. Historical, social and economic factors, together with an ethnically dispersed population, have resulted in the decline of the Livonian population, with only a small group surviving in the 21st century. In 2011, there were 250 people who claimed Livonian ethnicity in Latvia. History Prehistory The exact date of migration of Livonians to the region has been disputed. "The Livonians claim to have inhabited their present homeland for over 5,000 years." "The Fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gauja
The Gauja River ( et, Koiva jõgi, german: Livländische Aa) is a river in the Vidzeme region of Latvia. It is the only large river of Latvia that begins and ends its flow in Latvia. Its length is 460 km, of which 93.5 km (approximately one-fifth) are in the Gauja National Park. In this part, the Gauja River flows through the Gauja valley, which is 1 to 2.5 km wide, and the maximum depth near Sigulda is 85 m. Thus, Gauja is the longest river of Latvia when we count only the parts of the river in the country's territory. Daugava has only 367 km in Latvia, while the whole river is over 1000 km. The sandstone rocks on the banks of the Gauja and its adjoining rivers started forming 370 to 300 million years ago during the Devonian period. History Before the 13th century, the Gauja River used to serve as a trade route and border river between the Livonian and Latgalian lands. In some territories, they used to live mixed together.
